<h2>Problem 98</h2>
<div style="color:#666;font-size:80%;">17 June 2005</div><br />
<div class="problem_content">
<p>By replacing each of the letters in the word CARE with 1, 2, 9, and 6 respectively, we form a square number: 1296 = 36<img src="" style="display:none;" alt="^(" /><sup>2</sup><img src="" style="display:none;" alt=")" />. What is remarkable is that, by using the same digital substitutions, the anagram, RACE, also forms a square number: 9216 = 96<img src="" style="display:none;" alt="^(" /><sup>2</sup><img src="" style="display:none;" alt=")" />. We shall call CARE (and RACE) a square anagram word pair and specify further that leading zeroes are not permitted, neither may a different letter have the same digital value as another letter.</p>
<p>Using <a href='project/words.txt'>words.txt</a> (right click and 'Save Link/Target As...'), a 16K text file containing nearly two-thousand common English words, find all the square anagram word pairs (a palindromic word is NOT considered to be an anagram of itself).</p>
<p>What is the largest square number formed by any member of such a pair?</p>
<p class='info'>NOTE: All anagrams formed must be contained in the given text file.</p>
